Absolutely loving the game.
The main thing I dislike so far is also my own fault. When zooming around in space, you can speed up time to zip anywhere pretty fast - which is nice. But then because its the efficient thing to do, I do it all the time, and it becomes a weird min/max thing where I'm no longer enjoying the atmosphere. But one cant not have it, or heading to and from missions would slowly kill the game's momentum.
IIRC the achievements suggests there might be warzones later on which introduce a bit of pep into the ride. Yet I wonder if having boosting fuel as a resource would make the speedy-time more engaging - where judging acceleration/deceleration burn rates becomes a quietly learned skill.
That said, maybe that kind of ship exists later in the game - its still early days for me. Hopefully there's an asteroid field rally or a chase sequence or two in my future. As at the moment, every mission is a straight-line time-skip away.
Not to be all negative though, its a great game and I'm having a lot of fun with it. Good vibes, good music, good systemic interactions, and just enough flavour text that its interesting without being...as wordy as me
edit: if you get seen & shot by ships then there's an emergency fuel thing after all. cool
